SELECTING"MACHINE FOR DICTATING THE PUNCHING OF HOLE S IN JACQUARD .CABDS.

Application filed F bruar 24, 1927. Serial No. 170,41. Q

, My invention relates to machines for the raising of the heddles in the loom to produce a certain weave, and pattern.

' To correctly located and punch the holes in jacquard cards is a'highly skilled art and has heretofore been done by hand, and that only by highly skilled operators.

It is the object of my 11'1V6I1t1011 so to simplify this operation that jacquard cards may be punched quite readily without the requirement of highly skilled labor. .To' this end, I have devised a duplex selecting mechanism to be used in connection with the regular jacquard card punching machine, known in the trade as a repeateiywhereby master cards of simple punching, used in my new machine, dictate which punches shall be active to produce the desired weaves.

My invention is a duplex selecting-meclr anism having two selecting cylinders, two series of needles, two series of hooks,'and

two grrfie traines. operating s1multaneously,.

controlling one series of slidablerods or locking bolts of the punching machine. fI divide the process into two distinct steps,

though operating simultaneously, first dictatingthe punching for the pattern, and the second the punching for the weave.v To this end, my invention comprises a cylinder overt which is adapted topass aseries of cards or continuous strip of paper perforated tounlock punchesto produce the desired pattern, without regard to the weave. Back of this I provide another cylinder over which a V series of master cards is adapted to pass,-

these cards being perforated to unlock punches to produce correct punching of the jacquard cards for the kindof weave de sired. The weave cylinder is the determining factor, i. e.: the pattern cylinder may lock the punches to make the pattern, the v weave cylinder will unlock some of these to put the proper weave in the pattern.

Above the punches are rods or looks normallv holding the punches operative to punch holes in the jacquard cards. When any of these rods are retracted their punches become inoperative, and holes are not formed in tliejacquard cards. A series of horizontal hooks arranged above the before am tioned. cylindersare connected tothe ends of these rods, long hooks reachingoverthe pattern cylinder and shorthooks'over. the weave or master cardcylinder. They'are so arranged thata long hook and a short hook are connected to the endof each rod, so that any punch may be rende'red inactive by its lock or rod being retracted by a'pu ll upon either the longer short hook connected with it. p 1 a The hooks all pass throughslotted plates or grids which are pulled out'regulai 'ly with every operation or the punching fmechanism, so that all the hooks wou ld be pulled out atevery operation; if they were all allowed to remain in operative relation with the slottedplate or grid. To render certain hooks inoperativc,'a series of vertical needles is arranged 'inconnection with each series of hooks'whereby hooks may beraisedito. an inactive position, and these needles are inovedto" dictatethe action of the punches ,by' means of the before mentioned cylinders with the perforate'dpaper strip and the master cards. v I f I 'In order that the operation may be more fully followed and understood, append the following detailed description of my invention, in connection with the accompanying drawings, in which: I

For the purpose'ot illustrating my invention I. have shown in the accompanying drawingsone form thereof which is at presa, 1,eee,eoo i ent preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumcntalities of which my invention consists can be variouslyarranged and organized and that my in vention is not limited to the precise arrangen'ient and organization of the instrumentalities as herein shown and described.

Referring to Fig. 1, the punching machine comprises punches 1O slidable vertically in Below the punches a" the machine frame. perforated table 11 is arranged to carry the jacquard cards 12 to be punched and is operable vertically with respect to the punches by means of cams on a shaft 13 which is a regularly driven shaft in the machine. Only one row of ten punches is shown in the drawing, but it understood that there are any number of these rows across the front of the machine, according to the length and width of the jacquard card and the spacing of the perforations.

Above each punch is its lock, the projecting end of a slidable rod 14, which is normally held in locking position by springs 15. That is, the ends of rods 14 that project above punches 1O lock those punches against vertical movement, so that they will perforate the jacquard card when it is raised against them in the operation of table 11. To the rear end of each rod 141 are two wire Connections, one 16 connected with a long hook 18 and 17 connected with a short hook-19.

shown clearly in Figs. 1, 2, and 5, both the long and short hooks pass through a grid consisting of vertical bars 20 and horizontal bars 21 upon which latter the hooks rest and are bent to restrain them from the forward pull exerted by springs 15. Only one verti- "al row of these hooks is shown in Fig. l, but as seen by Fig. 2 there are supposed to be as many rows in width as there are rows, of punches required in the leng ofthe card to be punched.

The long hooks 18 extend through to the rear of whatI call my selecting machine where they pass through a guide plate 22 and grifle frame 23 beyond which their ends are doubled back to form heads 18. Gruide plate 22 is fixed to the machine frame 24 and is provided with vertical slots 25, 1. through each of which passes one of the long hooks 18. Griffe frame 23 has similar vertical slots 26, one foreach long hook. These Slots are too narrow to allow the passage of the hook heads 18" therethrough but they have horizontally aligned. enlargements 26 through which the hook ends may freely iass.

l The griffe plate is slidably mounted on frame 2d, as will be hereinafter described, and when it is moved forward from its normal position, Figs. 1 and it, it will pull all agroup of vertical needles 27arranged be-' side hooks 18 and each needle has an offset 27 which embraces one of said hooks, so that by raising a needle, as the one marked in Fig. 4, its hook may be raised to bring its head in line with enlargen'ient'2o of its slot as shown marked a in Fi 4. In its .7 b

regular movement forward, all the hooks that have been so raised by their needles will remain unaffected and allow the punches connected. with them to perforate the jacquard card, but all the hooks that have not been so raised will unlock their punches.

Needles 27 are suspended in the machine as'at 28, Fig. 1, and pass downward, one beside each hook, in regular formation, pass ing slidably through a perforated guide plate 29, and directly beneath them is arranged a cylinder 80, which is vertically movable against the needle ends. In the drawings cylinder 30 is shown as of .four sided form, presenting aflat face to the needle ends, said face being perforated'in alignment with the needles, so in an upward moven'ient of the cylinder, the needle ends 7 will all enter holes and not be operated.

A paper strip. or series of cards represent- 7 ed atp, Fig. 1, is adapted to lee-passed over cylinder 30, and has perforations corresponding with certain of the perforations in said cylinder,; forming a pattern, by which means certain needles may be prevented from entering the holes in the cylinder and be moved upward, carrying their-hooks, and

certain other needles passing through perforations in the paper strip will not be affected. v

Paper strip 19, may be perforated by machine or by hand in a simple manner, without regard to the form of weave desired, but

merely dictating the pattern or color scheme of the design intended for the jacquard cards.

I have arranged that the short hooks 19,

each connected to a punch lock as are the long hooks, shall separatelydictate the form of weave desired. To this end the short hooks are hooked at their rear ends as at 19 and pass through a grilfe frame which consists of thin plate bars d0 arranged vertically between the vertical rows of hooks. The long hooks pass freely between these bars and are unaffected in any way, but the hooked ends 19 of the short hooks are arranged normally tov catch over the edges of the bars, so that when this griffe frame is moved forward, see F ig. 1, it will pull all iii) such short hooks and unlock their punches.

Above this normal position of'each short hook, a slot 40 is provided in the griife bar 40, of sufiicient depth to allow a hook to be unaffected by the movement of the grlfie bars, when it is raised so that its hooked end' 19 aligns with its slot as indicated at- 0 in Fig-6. In order to thus raise certain short hooks to inactive position, I: provide another series of'vertical needles 41, having 7 offsets 41, Fig. 1, embracing the short hooks,- in exactlythe same manner as needles 27 embraced the long hooks. Needles 41 are similarly mounted to needles 27, and. directly beneath them is arranged a cylinder-'42, which may be similar in every wayand similarly mounted to cylinder 30.

A series of master cards, represented at r,

Flgii l, is arranged to pass over cylinder 42. and the perforations of these master cards cause'certain needles 41 to act to dictate the punching of holes in the jacquard card, just as did the perforated strip 77 on cylinder 30. These master cards may be perforated by machine or by'hand, in. a simple manner,

without regard to the pattern or color scheme desired, but merely dictating the form of weave as satin, twill, or the like; -The resuit is that certain holes in thejacquard card, as w-m Fig. 3, are dictated by the paper strip on cylinder 30 and determine the raising of heddles in the loom in accordance with the pattern, and'the intermediate holes 3/ are dictated by the master'cards on cylinder 42 and determine the movement of heddles in theloom, four to one or seven to one. or any combination, to produce a desired form of weave.

Griife frames 23 and. 40 are moved back and forth at regular intervals synchronously with movements of the punching machine.

For instance, as shown in Fig. 1, the grifi'e ,7

frames may be connected together by a yoke 43 pivotally connected with a roden arm 44. The roden arm may be connected by rod 45, bell crank 46, and link 47 with a lever 48, adgiipted to be moved by the moving punch ta e.

Cylinders 30 and 42 may be moved up and down and given step by step quarter turn by the following means, referring to Figs. 7 and, 8.

The shafts of these cylinders are mounted in bearings in a common frame 50 at each side of the selecting machine frame 24, and

carry at one end star wheels 51, actuated by wheels 52, which receive motion from vertical shafts 53 by means of miter ears 54. As these parts are all carried by fi ames 50 and are adapted to be raised and lowered,

- shafts 53 have slot and pin connected ends 55 mounted in the fixed frame 24 and driven by miter gears from a shaft 56 which extends rearwardly from the punching machine, and which is rotated 1n time with the punching machine, by means not shown, as it forms no part of my invention. Y Miter gears 57, also on shaft 56, through the, equal gears 58- drive a cam shaft 59, which carrieson each end cams 60. These cams are adapted to raise and lower rods 61,

mounted to slide vertically in brackets on- 7 the machine frame, and to which frames 50 are connectedonboth sides of the machine.

Prior to starting the machine, a linked series of'master cards are hung on cylinder 42 and the perforated paper strip is placed on cylinder 30, both being provided with margin holes for engagement with pins :11,

vFig. 8, at the ends of the cylinders for the purpose of alignment. 1 Y e The machine is then started, and cams 60 raise frames 50 carrying both cylinders against the lower ends of the two series of needles 27and 41. 'The needles that pass through holes aresnot moved upward and the hooks which they embrace are pulled by the movement of frame 43 so that the locks of their punches are retracted and holes are not punched. Similarly the needles that are raised by striking imperforate portions of the master card or. paperstrip, raise their hooks to the levelwhere they are unaffected by movement of griffe' frames 23 and 40, and

their punches remain locked and therefore punch holes in the jacquard card which has been placed on table 11in the punching machine. As the hooks are arranged} in pairs, one long one and one short one controlling each punch lock, it is only necessary for one of them to be pulled to unlock a punch. Along hookmay be raised to position 22, Fig. 4, by cylinder 30, and dono pulling, but its shorter mate, which may be t, Fig. 6, remaining unraised by cylinder42,

will be pulled by griffe frame 40 toyretract the locking rod which is connected with this pair of hooks.
